What membrane allows only some materials to move in and out of the cell?
The cell membrane, which is a lipid bilayer, will only allow some things in and allow others to go out of the cell.
What is cell membrane permeability?
It is the ability of the membrane to allow ions and/or particles to cross.
What does a gated channel in a cell membrane allow?
osmosis
Is a cell membrane invironment?
The cell membrane is somewhat of an environment.. cell membranes have many proteins inside them.. the proteins regulate the cell structure, allow cell-cell interaction, and allow passage of materials through the membrane. There also steroids in the membrane that regulate its shape.. and there are also various sugars / glycoproteins in the membrane. Also, one important thing to realize is that the inside of the cell membrane is NON polar.. the outside is polar however.
Which part of the cell surrounds the cell and allows molecules in and out this cell part also has holes in it and is said to be semi-permeable?
The cell membrane is the thing that surrounds the cell. The cell membrane contains proteins that allow active transport of molecules in and out of the cell.
How do structures within cell allow the cell to be specialized?
The structures allow the cell to perform specific functions.
What membrane allows only some materials to move in and out of the cell?
The cell membrane, which is a lipid bilayer, will only allow some things in and allow others to go out of the cell.
Which part of an animal cell lets food water and oxygen pass in and out?
The cell membrane contains receptors that allow or block passage of various molecules.
What supports the cell and allow parts to move?
cell membrane
What is cell membrane permeability?
It is the ability of the membrane to allow ions and/or particles to cross.
What is the funtion of the cell membrane?
The function of the cell membrane is to allow materials that are needed into the cell and the materials that are not needed and/or a waste product are taken out of the cell.

Membrane junctions that allow nutrients or ions to flow from cell to cell are?
Desmosomes
Why is a cell membrane is very thin?
To allow necessary chemicals in and out of the cell.
Does the cell membrane have tiny holes that allow materials to pass into and out of the cell?
yes
